I am using a 2port USB KVM switch, to which a DELL usb keyboard w/ 2 extra usb ports is attached.

I can use the keyboard and monitor fine, so the KV part is ok. However, the mouse, which is connected into one of the spare usb ports on the keyboard does not function.

Here is output from lsusb:

Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000

Bus 002 Device 014: ID 046d:c016: Logitech, Inc. Optical Mouse
Bus 001 Device 001: ID 0000:0000

OK - it recognizes my mouse.

Below is the output for the USB controller portion of lspci -vxx:

I'm not understanding this - any comments as to why the mouse isn't working?

Hmm what kernel do you use? I remember having had an issue withsome 2.6.x kernel (if I remember correctly up to 2.6.11) with kvm switches and mice connected to it.

Temporary workaround: get a PS/2-to-USB connector

Thanks for the replies.

I'm using kernel 2.4.31 and slackware 10.2

Could try the ps/2 to usb but that circumvents using the KVM switch. A ps/2 mouse works; tried that already.

I know I'm close - the above printouts note that my mouse is detected.

And the keyboard works just fine, so detection is ok through the KVM (at least for the keybard).

Any more comments??

I think the problem is that the mouse is plugged in through the keyboard.. Are you able to try connect it direct to pc?
see both devices are sharing the same Device ID. that can't be good surely. Are the keyboard and mouse both USB1.1 or 2
So the mouse is not working in XWindows? Which option have you selected in /etc/X11/Xorg.conf in the mouse section.
try set to 'auto' rather than 'usb' or whatever it is now.
also, try unplug the mouse and then plug it back in again.
then #tail /var/log/messages
maybe this will show up what the problem is...

Graz,

Thanks for the input. Yes, mouse is plugged into one of the two usb ports on my keyboard. Here are answers to your questions:

1. Can't connect directly to PC either.
2. key/mouse are usb1.1 (I assume)
3. Mouse not working under XWin or terminal mode
4. tail -f /var/log/messages is below after unplugging/replugging into another keyboard usb port:

here is output after unplugging from keybard and then plugging into PC usb port:

5. xorg.conf below:
ection "InputDevice"

# Identifier and driver

Identifier "Mouse1"
Driver "mouse"
Option "Protocol" "Auto"
Option "Device" "/dev/mouse"

InputDevice "Mouse1" "CorePointer"
InputDevice "Keyboard1" "CoreKeyboard"

Every other reference to "mouse" is commented out.

Still can't get it to work. I would think it is common to plug your usb mouse into your usb keyboard.

Any more ideas??

thanks.

Have a look in /etc/rc.modules.conf and uncomment /sbin/modprobe hid
Reboot and see if that helps.

Actually just modprobe hid as root from the console might help.

Thanks arubin - didn't help. Uncommented, saved, then exited and rebooted. Still no mouse.

The ps/2 mouse is the one that works.

Can't see how my situation is so difficult, and why I can't figure it out. I have successfuly mounted a usb thumbdrive into the second usb port of my PC. But if I stick my mouse directly into the same port, it isn't recognized.

Dell keyboard model# SK-8135.

Does mouse work when you stick it in separate usb port?

AH,

Thanks for your input.

No, mouse does not work when plugged into a spare usb port. I know the spare port works because I can mount a usb thumbdrive into it and yank files to/from the drive.

Also, I tried plugging the thumbdrive into one of the keyboard usb ports - can't get it to work either.

One question: The following statement executes during boot from rc.d/rc.gpm - maybe it's causing confusion??

Starting gpm: /usr/sbin/gpm -m /dev/mouse -t ps2

Chmod -x /etc/rc.d/rc.gpm and check if anything changes. Strange that mouse doesn't work on a separate usb port. I recommend firstly to get mouse working on a separate usb port because then you will know that this is not mouse problem. Then you could plug it into the keyboard and explore the problem there.

okay - i have read a bunch saying that the GPM would stop the mouse working in XWindows..
It should however still work off the console if this is loaded.. so you have tried on a plain USB port with no change. Lets see plug direct into USB port again, what happens in /var/log/messages ? I think the USB hub in kboard might confuse it.
Then, run #mouseconfig again and choose PS/2 as the device type.
You can chooose to disable GPM at ths point and delete the line from /etc/rc.d/rc.gpm

Probably worth noting that udev does not stick its nose in and do its work in your output .... Its looks pretty busy on my machine

Also, i am sure i needed to have UHCI support enabled before mine would work. check #lsmod and ensure everything required is loaded - here is my related output

ohci_hcd 16196 0
usbmouse 4032 0 <-- funnily enough this seems new to me...

ehci_hcd 24520 0
usbcore 100676 6 ohci_hcd,usbmouse,usbhid,uhci_hcd,ehci_hcd

Also, re: the qestion about the idea of plugging the mouse into the keyboard... I am almost certain that there would have to be latency issues when configuring this way... i know that in windows XP i plugged my DELL mouse into a dell keyboard at the office and it was fairly much useless... it worked but not in the way it should.. it was almost like using remote assistance

I think it ought ot be

Starting gpm: /usr/sbin/gpm -m /dev/mouse -t imps2

Another idea to try testing if you are getting any input. You might need to do this as root.

cd /dev/input
xxd event0

Wiggle the mouse about to see if you get numbers scrolling across the screen. If you do Ctrl-C to exit

If not try
xxd event1

and

xxd event2

As I know, gpm is only used for mouse support in console and sometimes it conflicts with X server mouse support. Please correct, if I am wrong. Thanks.

Yep - that is my understanding of it as well.. gpm works fine for me on console and x server however.. no probs.
